This entry represents the nuclease (NUS) domain of endonuclease Bax1 [1], a dual DNA endonuclease probably involved in nucleotide excision repair (NER) [1]. This domain cleaves the 3' side of a DNA bubble, while the N-terminal domain of Bax1 cleaves the 5' side [1].	Domain
A, C, E	PF00271	Helicase conserved C-terminal domain (Helicase_C)	Helicase conserved C-terminal domain	The Prosite family is restricted to DEAD/H helicases, whereas this domain family is found in a wide variety of helicases and helicase related proteins. It may be that this is not an autonomously folding unit, but an integral part of the helicase.	Domain

XPB is essential for transcription, nucleotide excision repair, and TFIIH functional assembly. The domain is a damage rec ...	This domain is found in the N-terminal region of xeroderma pigmentosum group B (XPB) helicase present in Archaeoglobus fulgidus. XPB is essential for transcription, nucleotide excision repair, and TFIIH functional assembly. The domain is a damage recognition domain (DRD) which allows XPB to unwind damaged DNA as needed for nucleotide excision repair [1].	Domain
